A few months ago I signed up for a FYE back stage pass, which I basically took to be a CVS extracare card type of thing. It turns out they've been taking $10+ dollars out of my account every month even though they never told me that it had a monthly fee, and I never provided my card for that purpose. So I call them to try and get it closed, and they won't let me because I don't know my membership number which I'm 90% sure they never provided me with. All they gave me in the store is a cheap key ring card to scan for 10% off.

Wtf am I supposed to do about that? I'm honestly about to just say I lost my debit card so I can get a new one, would that work? I've also been planning to change banks for awhile anyway so I might do that before the month is up.
